Description

Can nut for keeping distance of flash board and fixing

The present invention relates to a formwork fixing nut for fixing while maintaining the spacing of the formwork buried in the wall of the concrete building, in particular to facilitate the coupling of nuts and cones, and to prevent falling back even in the event of a dormitory as well as a dormitory. will be.

In general, when constructing concrete buildings, formwork is installed so that concrete can be poured. At this time, the nut is used as the means for maintaining and fixing the formwork to maintain the space between the formwork to be installed.

The cone nut is molded of a plastic material and pressurized to the cone 100 and the coupling hole 110 formed in the center of the cone 100 and the coupling hole 110 formed with the concave-convex protrusion 120 is formed at a predetermined interval in the center. The nut 200 consisting of a head portion 210 and a polygonal fitting protrusion 220 formed on the lower end at the upper end thereof is coupled to each other by pressing, and the cone nut is formed on both sides of the Sepha bolt having bolts formed at both ends. Tighten one end of the tie bolt penetrating from the outside of the formwork to the cone nut in the state of maintaining the spacing of the formwork, and fasten the formwork by tightening the wing nut on the other end of the tie bolt, and then cast concrete on the fixed formwork. When the concrete is hardened, the formwork is removed, the cone nut holding the formwork is removed, and the part where the nut was located is buried.

However, when the disadvantage of the cone nut having the above structure is frequently used, the convex and convex protrusion 120 holding the nut 200 coupled to the coupling hole 110 of the cone 100 and the cone 100 is worn out. When the nut is loosened and the nut is fastened or dismantled, the cone 200 is turned away from the cone 100. Therefore, the nut 200 has to be fastened or dismantled using a separate tool. .

In addition, the cone 100 and the nut 200 are simply formed to be fitted by pressing in only one side, so that the cone 100 and the nut 200 that are coupled have a problem of being easily separated when they become loose. .

Therefore, it is impossible to reuse the cone due to the above problems, so each construction costs a lot of construction costs because it has to use a new nut.

Therefore, the present invention has been devised to solve the above-mentioned problems. When the nut is pressed into the inside of the cone of the metal molded into the cone of the cone formed of the synthetic resin material, the coupling of the cone is forcibly pressed. The inner surface of the ball is deformed into the shape of the nut so that it can be combined in perfect contact with the insert method such as insert injection, but the manufacturing is simple and the cone and the nut are not separated.

To this end, the inner diameter of the coupling hole of the cone formed so that the nut is fitted in the center is formed in a circular shape, and the fitting protrusion of the nut is formed into a polygon having an angled edge that is a little larger than the inner diameter of the coupling hole. The pressure is forced to make the inner surface of the coupling hole deform so that it is in close contact with the fitting protrusion of the nut.

In addition, in order to prevent the nut from being inserted into the cone is formed in the upper end of the engaging hole formed in the engaging jaw and the head portion of the nut to form a stepped portion so that the stepped portion is caught on the locking step.

Therefore, as described above, the present invention has the same effect as that of insert injection because the cone and the nut are firmly coupled with each other when they are combined, and the coupling hole of the cone is tightly enclosed with the nut so as not to be pulled out. In addition, it is easy to use and reuse the cone can provide the effect of reducing the material cost.

Figure 2 is a perspective view and a bottom view of the nut is coupled to the cone of the present invention.
3 is a cross-sectional view of the nut is coupled to the cone of the present invention.
Figure 4 is a state of use of the cone of the present invention.
5 is a perspective view showing a structure of a conventional cone nut.

Hereinafter, the present invention will be described with reference to the accompanying drawings.

1 and 2 show the step of the nut is coupled to the coupling hole of the cone formed of the plastic material of the present invention and Figure 3 shows a cross-sectional view of the cone and the nut of the coupling step.

As shown in Fig. 1 and 2, the structure of the nut of the present invention is made of a plastic material, the coupling hole 11 and the upper edge of the coupling hole 11 of a predetermined diameter made of a circular shape in the center of the nut ( Cone 10 having a seating portion 12 on which the head part 22 of 20 is seated, and a multiplicity of fitting protrusions 21 slightly larger than the inner diameter of the coupling hole 11 formed in the cone 10 and The nut 20 composed of the head portion 22 on the upper side is formed to be pressed by force with a press.

At this time, a nut formed in a polygon having a relatively larger outer diameter connecting a corner edge of a corner than the inner diameter of the coupling hole 11 to the inner diameter of the coupling hole 11 of a predetermined diameter formed in the center of the cone ( When the fitting protrusion 21 of 20 is pressed by using a press, the shape of the fitting protrusion 21 is formed in a polygonal shape by the angled edge of the nut 20 in the inner surface of the coupling hole 11 due to the nature of the plastic material. As the inner surface of the coupling hole 11 is completely deformed while being fitted into the fitting protrusion 21 of the nut 20, it is to be tightly coupled.

This assembly has the same effect as the injection molding of the complicated and expensive one-piece manufacturing process to combine the cone (10) and the nut (20) is a circular coupling hole 11 of the cone and the fitting protrusion of the nut angled corners It is made of a polygon with sides so that it is forced to fit without the need for correct positioning.
Therefore, the nut 20 will be prevented from turning away from the cone 10.

In this case, as shown in FIG. 3, a locking jaw 13 is formed to be inserted into the wall surface on which the seating portion 12 of the cone 10 is formed, and the head portion of the nut 20 is used as the locking jaw 13. The head of the nut 20 is formed due to the characteristics of the plastic material of the cone 10 when the nut 20 is pressed by the press by forming the step 23 in the head portion 22 to catch the 22. It is possible to force the fitting portion 22 and thus can be more firmly fixed to the combination of the cone 10 and the nut 20 will be prevented from falling out even if a waste dome occurs.

The hooking jaw 13 of the cone 10 forms a curved portion 13a to facilitate the fitting of the head portion 22 when the nut 20 is coupled thereto.

Therefore, as described above, the cone of the present invention makes use of the characteristics of the material of the cone 10 formed of a plastic material, so that the nut 20 formed of metal is pressed by a press strongly to the cone 10 of the cone 10. As the fitting protrusion 21 of the nut 20 is fitted into the coupling hole 11, the inner surface of the coupling hole 11 is deformed in the form of the fitting protrusion 21 to be completely in close contact with each other. When the cone 10 and the nut 20 is prevented, it is possible to reuse it no matter how many times it is used. Also, when the cone 10 and the nut 20 are combined, the cone has a locking jaw and the head of the nut. It is formed by the stepped to be more firmly fixed.
